There’s something special about moms, right? So, today’s post is about an under-appreciated group of moms (you guessed it), Arizona Black Rattlesnakes!

Human moms – you think you have it tough? Rattlesnake maternal duties may only last a couple weeks, but during that time they may have to protect their kids from extreme temperatures, a suite of predators, annoying (and deadly?) squirrels, and clumsy humans with cameras… By the time they give birth, mother rattlesnakes likely haven’t eaten in weeks or even months, but they wait another couple weeks to give full attention to their newborns. So here’s to you rattlesnake mommies!

We’ll start with the most famous of all, Cap Mama, who showed us what a typical day is like for a new rattlesnake family:

What a beautiful family she has!

Sigma may have been one of our smaller mothers, but what she lacked in size she made up for in bravery:

We’ve been lucky enough to see Woody and Alice with two different litters.

So now you know that rattlesnakes take care of their kids. Sometimes they take care of their friends’ kids too!?!
